SHADE, CURTAIN, OR AWNING ROLLER. STOP.

Application iled April 17, 1922.

To all whom t may con-oem.'

Be it known that I, GEORGE D. HILL, a citizen of the United States, and a resident of Norfolk, in the county of Norfolk and State of Virginia,have invented certain new and useful Improvements in Shade, Curtain, or Awning Roller Stops, of which the following is a specification.

This inventionrelates to stops especially adapted for use in connection with shade, curtains, awnings or the like and is any imT provement over the construction illustrated .f

in ymy United States Patent Number 1,166,- 683. i

Briefly stated, the improvement residing in this application is in the nature of an at- Y tachment whichmay be readily and conveniently connected to one end of a shade, curtain or awning roller so as to limit the rotation of the roller and consequently'provide a reliable means whereby to limit the movement of the shade or the like when drawn downwardly. 4

A further object is to provide a roller attachment whiclimay be inserted into one` end of the roller and connected to an ordinary bracket in such a manner that the major portion of the attachment'is `concealed.

While the invention is illustrated in the drawing as employed in connection with a shade, it is quite obvious that the inventive idea involved may be vemployed in connection with a curtain, awning or other body which is wrapped about a roller.

` The invention forming the subject mat- `-ter of this application also aims to provide an attachment which is of highly simplified cheapv to construction, durable in use and manufacture.

Other objects and advantages of the invention will be apparent during the coursel of the following description.

In the accompanying drawings forming a part of this application and in which like.

numeralsare employed todesignate like parts throughout the same,

Figure l is a side elevation of l the at-` tachment in use. f v Figure 2 is a longitudinal sectional view through the same applied.

Serialy No. 553,657.

Figure 5 is a plan view of the blank from which the collar is formed.

Figure 6 is a sectional view illustrating a slightly modiiied form of the invention, the shade and roller also being shown in section.

Figure 7 is a group view of the construction illustrated in Figure 6. i

Figure 8 is a Ygroup perspective of the form of the invention'illustrated in Figures 6 and?.

In the drawing, the numeral 5 designates a roller having one end formed with a pintleA 6 to which the attachment is adapted to be connected. v

.As previously stated, the attachment is adapted to Ilimit the movement of the roller and to this end I provide a spindle 7 having one end formed with an enlargement S provided 'with a socket 9.` As illustrated in Figure 3, the socket 9 has one side flat yto correspond to the flat side 10k of the pintle 6- and when the pintle is received within the socket 9 a driving connection is provided. It will be seen, however, that the pintle 6 is of the ordinary construction and that ,the fiat side 10 may be 1provided by means of a file thereby enabling the spindle 7 to be detachably connected to the pintle.

A; spiral body 11 is mounted on the spindle @and has one end portion i2 extended throughl The other end of the spiral body 1l is formed with a return bend 14 which serves as a stop element for a collar designated by the numeral 16.

The collar is mounted upon the spiral body and is formed with a pair of inwardly vextending lugs 17 adapted to fit between the convolutions of the spiral body so that when the spiral body is rotated the collar will be moved longitudinally of the spindle. Of 'course,-one ofthe inwardlydirected lugs is arranged slightly in advance of the other lug as illustrated in Figure 4.

The collar 16 is formed from the blank illustrated in Figure 5 wherein the blank is shown as being provided with extensions which are interlocked in the manner illustrated in Figure 4 to define a radial rib or member 19 whichisreceived within a `longihousing 21. As the -radial rib 19 is received within the slot 2O the collar '16 is, of course, held against rotation so that when the spiral body is rotated the collar will be moved longitudinally. The slot 20 extends out through the end of the housing 21 adjacent the roller and consequently permits the spindle, the spiral body, andthe collar to be withdrawn as a unit. When the parts 11, 16 and 21 are withdrawn, the collar 16 may be manually adjusted on the spiral body so as to limit the movement of the fabric body 23 tacked or otherwise secured `to the roller. If itis desired-'to allow only ya slight movement to the fabric body 23 the collar 16 may be positioned 'somewhat close to the return bend 14 as illustrated in Figure 2, and if it is desired to increase the Zone of movement ofthe body 23 the collar is positioned near the outer end of the spindle. kIt will be apparent, of course, that the return bend 1'4 serves as a stop element for limiting the longitudinal movement of the collar.

In summarizing, it will be lobserved that the attachment may be readilyan'd conveniently connected to the roller "without a substantial alteration inthe construction yof the roller 'and it will Vbe further seen that the appearance of the roller` or the "body carried thereby is not marred. A bracket '25 may be formed integral with the housing 20 or may be detachably connected thereto. The bracket serves as 'a convenient 'means for secu-ring the roller and the attachment to a suitable support such as a window frame. y

If desired, the Vinvention may "be'bui'lt `into the roller 4'() in the manner illustrated 'in Figures 6 to '8 inclusive in which yfigures the fabricbody 41 is shown wound about'the roller.

The housing 42 which is of vtubular formation is inserted into a socket in one end of the roller ,and the housing has one end formed with a radial attaching flange 43 formed with claws 44 which bite into 'the roller and thereby anchor the tubular housing inl position. A spindle- 45 is Areceived within the tubular housing 42 and "is provided with a spiral body '45 about which a collar 47 is arranged. In this form ofthe .invention the collar is provided 'with a radial rib 48 which is vreceived lwithin a longitudinally `extending slot '49 in the tubular housing whereby the Arotation of the spindle and the spiral body results inthe movement ofthe collar llongitudinally of the housing.

In carrying out this form of the invention one end of the spindle 45 Nis extended al short distancebeyond the tubular housing vand is l .squared as indicated at 51 for engagement with a bracket 52. The squared .end i351 of and the tubular housing with an annular flange 63 which serves as a means to hold the spindle in position.

In operation, the collar 47 is set at the proper position on the spiral body 4tl and when the fabric body 41 is pulled its movement will be limited by the collar engaging the return bend 5'5 on the spiral body.`

It 'will be seen that the attachment, Vwhen applied, is practically concealed and fur-ther that it doesnot in any way interfere with curtains which may be arranged close tothe shade. v

The foregoing illustrates that this Vinvention is lcapable of 'a variety of mechanical expressions and it is therefore understood that such minor changes tin arrangement and-y construction of parts may be lmade as will remain within 4the spirit of the Iinvention and 'the scope lof lwhat is claimed.

Attention is directed t0 lthe fact that the coil springs 11 and y46 have their ends formed with returned bends which constitute stop elements and limit the movements of the members 16 and 47 respectively. It will Vbe seen that the `coil springs yield to a limited extent `when the collars are'engaged with the said elements, and therefore, a yieldable means .is provided to limit the `downward fmovement of 'the shade. By yproviding a yieldable stop for the shadethe shade cannot be accident-ally pulled off the roller.

I claim 1. The combination with a roller having a'socket, of a spindle received in said socket,
